Abstract: 509,001. Floating targets steering. WEICHARDT, R., FREISTADT, W., and HICKE, J. Jan. 10, 1938, No. 2878/39. Divided out of Complete Specification of 508,974. [Class 20 (i)] [Also in Group XXXIII] A floating towable target is adapted to be arbitrarily deviated from the towing path so that it can move in a zig-zag manner for practice in bombing from the air. The steering means is attached to the front portion of the target which may be provided with lifting means to cause skimming at speed, and the target may comprise a flexible platform as described in Specification 508,974. The steering means may be hand or automatically operated and may be controlled either from the target itself or from the towing vessel. The automatic means may be electric, or gas or fluid under pressure and the power may be developed by means of a paddle or propeller operated by the movement of the target through the water. In the case where the steering is effected or controlled from the target itself, the steering cockpit is covered by an armoured hood 51 to protect the personnel and the actuating or control gear 50 for the rudders 46. The towing rope 52 may be attached to a towing hook 53 engaging a bow 54 on the target so that the target may be diverted from the line of tow as shown in Figure 2. When electrically controlled from the towing vessel the cables may be located within the towing lines. Compressed air and similar forms of pressure medium either for control of or to work the steering apparatus on the target may be transmitted in similar fashion from the towing vessel to the target. The steering of the target may be effected by actuating the rudder thereon by means of ropes actuated by a winch on the towing vessel.

Title: Improvements in condensing plant for steam and other vapours
IPC: F28B9/08
Filed: 1926-02-02
Abstract: 270,378. English Electric Co., Ltd., and Mather, J. W. Feb. 2, 1926. Surface condensers; combined jet and surface condensers; condenser systems. - In condensers for power plant involving the use of steam, vapours of carbon dioxide, sulphur dioxide, mercury &c. in which the vapours pass across a nest of cooling tubes, condensate is discharged through a liquid seal in order to counterbalance the diminution of pressure due to the resistance of the tubes, and is heated by being brought into contact with steam in the condition in which it enters the condenser or with exhaust steam from other sources. Condensate from a condenser 2, Fig. 2, passes down a pipe 3 and Hows over a haffle 13 into the chamber 12 from which it is withdrawn by a condensate pump 10. Steam enters the chamber 12 by a pipe 7, and air &c. is withdrawn from the chamber by a pipe 37 connected to the condenser near the air-withdrawal pipe 6. When steam and hot drips from auxiliary machinery are used for the re-heating, the pipe 7 may be a narrow pipe serving to equalize the pressures. The re-heating may be effected in a separate chamber 8, Fig. 4, to which condensate flows by the pipe 3. The liquid is raised bv an ejector 15, operated by water from the condensate pump, into an upper compartment 20 from which it falls as spray through steam admitted by a pipe 7. A pipe connection 21 serves for de-aerating. The condenser may be divided by partitions 26, Fig. 5, so as to leave a central compartment 29 down which condensate raised by the ejector 15 is sprayed for re-heating.

Patent GB-1138283-A (GB)
Title: Improvements in automatic exposure-control arrangements for photographic cameras
IPC: G03B7/085
Filed: 1966-01-24
Abstract: 1,138,283. Automatic exposure control. E. BERTRAM and W. BERTRAM. [trading as ERNST & WILHELM BERTRAM, FABRIK PHOTOTECHNISCHERMESSGERATE], Jan. 24, 1966 [Jan.25, 1965], No.3197/66. Headings G2A and G2E. [Also in Division Gl] The aperture of a diaphragm 3 loaded by a spring 8 is varied by causing the light passing through it and the camera objective 2 to fall on a photo-cell 6 which controls an electromagnetic transducer (e.g. a moving coil instrument); this applies a torque to the spring 8, and either the spring rate (i.e. the force/displacement characteristic) of the spring, or the response characteristic of the instrument, or both, can be varied so as to extend the range of light intensity to which the device is sensitive. As seen in Fig. 1, the device is shown as part of a cine-camera, the light beam 1 passing through lens 2 and diaphragm 3 to fall on film 5 being intermittently intercepted and reflected, by a rotating half-cone 4 acting as a shutter, to a photo-conductive cell 6. The output from the cell is coupled with the coil 10 of the instrument, inside which is the core magnet 11. Above and below the coil 10 are restoring springs 12 (corresponding to spring 8 in Fig. 1), which are secured at one end 12' to a radial arm 14 fixed to the spindle 13 of the coil, and at the other end 12" to an arm 17 of a disc held against the inside of the housing 9. The arms 17 can be rotated by hand, to a fine degree of adjustment, to vary the tensions of the springs 12, and hence the response. The core magnet 11 is formed with a non-uniform section, i. e. by having two parallel flattened portions 26, one of which is visible in Fig. 3 (not shown). Surrounding the coil is a keeper ring 27, having recesses (28, Fig. 3 not shown) therein. The core magnet can be manually rotated, by means of an arm 25, with respect to the recessed keeper ring, so affording a fine adjustment control of the orientation and magnitude of the magnetic field. It is thus possible to achieve mutual compatibility between the response characteristic of the moving coil instrument and the spring rate of the spring(s) 12, and so to achieve improved response, particularly in the lower brightness range.
